Abstract

Patente de Invenção: <B>"PROCESSO E INSTALAçãO PARA SOLDAGEM DE PEçAS DE ALUMìNIO OU DE LIGAS DE ALUMìNIO<D>". Descreve-se um processo sem participação de águas residuais para a soldagem de peças de alumínio e de ligas de alumínio, com a utilização de fundentes, especialmente à base de potássio e aluminato de flúor em suspensão aquosa. Como depois de um determinado período de tempo, a suspensão usada é substituída por suspensão fresca, sendo necessário limpar regularmente as aparelhagens, é gerada água residual que contém fundentes, por exemplo flúor aluminato de potássio. Estas águas residuais até agora foram eliminadas no meio ambiente. Verificou-se todavia agora que estas águas residuais podem ser recicladas no processo de soldagem após a separação do fundente. Desta maneira a incidência de águas residuais pode ser evitada mais ampla extensão possível. Como são freq³entemente empregados tencídeos e como estes também são reciclados, torna-se possível uma economia correspondente em tencídeo. Além disso, o meio ambiente será protegido de modo correspondente.Invention Patent: <B> "PROCESS AND INSTALLATION FOR WELDING ALUMINUM PIECES OR ALUMINUM ALLOYS <D>". A process without the participation of waste water for the welding of aluminum parts and aluminum alloys is described, with the use of fluxes, especially based on potassium and fluorine aluminate in aqueous suspension. As after a certain period of time, the used suspension is replaced by fresh suspension, and it is necessary to regularly clean the equipment, residual water is generated which contains fluxes, for example potassium aluminate fluoride. These waste waters have so far been disposed of in the environment. However, it has now been found that these wastewater can be recycled in the welding process after separation of the flux. In this way the incidence of wastewater can be avoided to the greatest extent possible. As Tencidae are frequently used and as they are also recycled, a corresponding Tencidian economy is possible. In addition, the environment will be protected accordingly.
